"[A]ppeal of non-final, or interlocutory orders, is an extraordinary measure." FXM, P.C. v. Gordon, 2007 WL 3491274, at *2 (N.D. Ga. Nov. 6, 2007) (citing In re Charter Co., 778 F.2d 617, 621 (11th Cir. 1985)). Interlocutory review is appropriate when the order involves: "a controlling question of law as to which there is a substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of the litigation."
